Beagle - my apologies, guilty as charged
I should, of course, refer to it as the Lightning II
, to avoid all misunderstanding.
Whilst the tiltrotors do indeed land like helos, as a conventional landing would lead to a nasty mess due to prop diameters, I am pretty sure that Boeing & Bell/Agusta would not be happy with them being called helicopters. The actual flying after take off is certainly not like a helo with the sales pitch being that they can do many things faster and further than a helo. Boeing are also allegedly developing an A400M size quad tilt rotor aircraft.
From history the Fairey Rotodyne (sp?) was certainly more like a helo than a tiltrotor is.
